Gas lens col body 1.60mm (t9/20) 45v43

Gas lens collet body for 1.60mm tungsten, part number 45V43, for WP9 and WP20 series TIG torches. Gas lens design laminarises shielding gas flow for extended coverage and reduced contamination risk. Enables longer torch-to-work distance. Replace when threads are stripped or gas flow is compromised.
